LABEC LBC-8 - Manual (Page 2)

Introduction
Congratulations on the choice of an Australian made quality product. Labec products are manufactured, tested and
calibrated to meet published standard specifications under our strict quality assurance guidelines.
This Instruction Manual is for the guidance of operators of Labec Water Baths and should be read before the water
bath is connected to the electricity supply.
It is hoped that this manual will supply all the information that the customer should require for satisfactory
operation of the water bath. If, however, there are any questions that remain unanswered then the customer should
contact our service department.
Unpacking
Remove all packing and protective wrapping from both interior and exterior of the water bath. Check the water bath
for any possible transit damage. Ensure all ordered accessories are present. If any physical damage or shortages
are evident, do not discard the packaging material until the water bath is inspected by the distributor, agent or
manufacturer.
NOTE: All claims for shortage or damage must be made within fourteen days (14) from delivery.
Subject to our standard published conditions of sale, we have reasonable grounds to believe that we have ensured,
so far as is reasonably practical, that the products listed in our catalogue and brochures have been designed and
constructed so as to be safe and without risk to health when properly installed and used in their environment by
appropriate and trained personnel, and where applicable, in accordance with our published instructions.
Installation
Electrical
This equipment must be tagged and tested according to AS/NZS3760:2010 prior to use and thereafter on
a regular basis dependent upon the environment.
It is preferable to locate the bath close to a power point and recommended that double adaptors are not used.
Check the total wattage if connecting to multi-point outlets. Check the rating plate for power requirements.
Installation is to be carried out by a qualified electrician in accordance with the power requirements of the product
specifications. Ensure the unit is Tag Tested prior to first power up.
Location
Select a location free from draught and away from direct sunlight or other heat source.
Circulating Pump
For the circulating pump fitted there will be two small holes at the end of the bath. The upper hole is the inlet and
sucks the water in and then pushes it out the lower outlet hole across the heating elements under the tray. Ensure
before the bath is ever turned on that the upper inlet holes are well covered at all times. Test the water pump is
circulating with your finger and if not you will need to push some water into the inlet hole using a hose or similar to
push the airlock out of the pump system.
Temperature Control
LABEC water baths are fitted with either digital temperature controller as per Appendix A, connected to the
element and cooling system. The water bath has been stringently tested before shipment to ensure all is in
working order.
Description of Controls
Set the desired temperature or heating level by adjusting the temperature controller as per Appendix A. A light on
the controller “OP1” will illuminate when power is being supplied to the elements. Set the Alarm AL4 in Level 2 of
the controller above the maximum temperature required about 5ºc above. Turn the cooling off above 30ºc.
Cooling System
The Cooling system uses a CFC free refrigeration compressor to cool the water in the bath. Turn if off above 30ºc
to reduce wear on the cooling system. The cooling will run continuously and the heaters will maintain the
temperature on the set value. Use “anti-freeze” when operating below 5ºc. Clean the cooling system air filter inlet
monthly by wiping with a damp cloth or vacuum cleaner.
